[PATCH v2 0/1] MR9400: winemac.drv: Use C99 bool instead of int for Boolean values.

[Brendan Shanks (＠bshanks)]

This largely applies to the variables and functions declared in `macdrv_cocoa.h`, which (currently) cannot use Win32 types.

Note that for ObjC method signatures, I'm following the advice of Google's [Objective-C Style Guide](https://google.github.io/styleguide/objcguide.html#bool-pitfalls) and sticking with ObjC `BOOL` in method signatures (like `- (void) setRetinaMode:(BOOL)mode`). I think the motivation behind that is to avoid confusion between `BOOL` and `bool` when overriding methods: on some architectures (ARM64) they're the same, on others (Intel) they aren't, so just stick with ObjC BOOL everywhere.
